Title: Thermodynamically stable crystal form of 4"-deoxy-4"-(epi)-methylamino avermectin b1a/b1b benzoic acid salt and processes for its preparation
Inventor: CVETOVICH RAYMOND
IPC: A01P7/04
Filed: 2000-09-07
Abstract: This invention is concerned with the most stable of four crystalline forms of the benzoic acid salt of 4"-deoxy-4"-epi-methyl-amino avermectin B1a/B1b a known agricultural insecticide, and processes for preparing it. The four crystalline forms that have been identified are designated as forms A, B, C and D, three of which are hydrates (B, C and D). The most thermodynamically stable crystalline form is the hemi-hydrate B. Knowing the most stable crystalline form and devising processes for producing the product in that form is extremely important that it provides bulk material with crystal homogeneity that is not going to transform to another crystal habit on storage.

IPC: H04L12/70
Filed: 1988-12-14
Abstract: In high-speed packet switching, packets of specific connections (CS1, CS2), e.g. speech, moving image, are to be handled with higher priority than packets of other connections (PS1, PS2, PS3), e.g. data, without delay jitter and without losses. 
<??>In a known method, a division is made into a line-switching component (for CS1, CS2) and a packet-switching component (for PS1, PS2, PS3). The line-switching component operates using synchronous time-division multiplexing. In each case, for example, 70 packets, each comprising 40 octets, are combined on each input line to form a frame. Without special measures, this would produce delays in each switching stage of the order of 40 x 70 x 8 bits = 22,400 bits; for each input of a switching stage 22,400 bits of memory space would be required. 
<??>According to the invention, all packets are divided in the exchange into packet parts of equal length and distributed among sub-frames. Switching is carried out on the basis of sub-frames. Delays and memory space requirements are reduced by the frame : sub-frame ratio. 
<??>Fixed positions are preferably allocated to the higher-priority connections (CS1, CS2) in each frame and each sub-frame for the entire duration of the connection. 
<??>Packet parts of the remaining packets are preferably arranged in sequence in remaining free positions and re-combined within each switching stage to form complete packets.

Novel steroids having in the 17-position the structure (wherein R is C 1-5  alkyl and R<SP>1</SP> is acyl of at most 20 carbon atoms) are prepared by acylation of the corresponding free 17#-ols with the appropriate acid chloride or anhydride. Other groups in the molecule may also undergo reaction during the acylation, e.g. hydroxy groups may be esterified and keto groups enol esterified, but they may be regenerated selectively by controlled hydrolysis. Alternatively, such groups may be protected before acylation, e.g. as ketals, enol ethers or tetrahydropyranyl ethers, and regenerated by hydrolysis subsequently. (1.Adamantyl)-acetic anhydride is prepared from (1-adamantyl)-acetic acid and acetic anhydride. The 17α - (1<SP>1</SP>,3<SP>1</SP>- alkadiynyl) - 17# - acyloxysteroids of the invention, which are stated to have estrogenic, progestational, claudogenic, ovulation - inhibiting and gonadotrophininhibiting properties, may be incorporated in pharmaceutical and veterinary compositions, e.g. tablets, injections, vaginal sponges and tampons.

Title: Grinding device for the reprofilling in site and continuously of a railroad track
Inventor: PANETTI R
IPC: E01B31/17
Filed: 1980-12-12
Abstract: Device intended to be displaced along track rails and comprising a frame (2) guided by the rail (1) provided with a grinding wheel (6) which grinds through its periphery. To uniformly distribute the wear resulting from contact with the rail on all its active surface, the grinding wheel (6) is driven, in addition to the continuous rotation supplied by a driving motor (7), in an alternating motion transverse to the track by means of an actuating mechanism. This actuating mechanism comprises a motor-gear assembly (13) driving an eccentric shaft (9) on the eccentric of which the movable support (8) is hinged. To avoid the formation of sinusoidal traces due to the grinding, the amplitude a of the reciprocal movement is related by the equation a SIMILAR l-f to the width l of the active surface of the grinding wheel and to the width f of the portion of the profile of the rail which is ground.
